Re: gib material In Sherline's YT vid, "Gib Installation" th-cam.com/video/FkoxaUCpvn8/w-d-xo.html Sherline VP Karl Rohlin states the gibs are a "plastic-glass mix" and "last vitually forever" @ ~7:10. I have a 'new to me' 4400 I added a headstock riser block to, and custom risers between cross slide and tools, and a custom tailstock. I use a 2.5hp DC treadmill motor, WITH the OEM controller, to take advantage of the integrated load accomidating, constant RPM feature all decent treadmills have, (don't throw out the OEM controller and go with the YT method. CNC machines have constant RPM circuitry. Why throw away that feature?) I setup my lathe and motor for maximum rigidity, turn stainless and use carbide insert tooling. Any other material is a breeze, if I get my DoC, speeds & feeds right. LOL I also bought a Sherline mill attachment and mill with my 4400, with good success. SInce my Sherline is used, there's wear. I'm in the midst of installing a new saddle and cross slide. Looking for tips on YT, I found a great tip about improving gib performance. "Improve the performance of a sherline gib" th-cam.com/video/XEQ-XlZRElw/w-d-xo.html The gist of the video is the cups in the gibs are too large for oil to 'manage' the depth. The video shows how to flat sand the gib contact surface, then use super glue to build up the backside of the gib, (the non-moving surface). It's easy to do with a decent flat surface and some sandpaper. The performance of the Sherline in the video is impressive, so the gib upgrade must work. GeoD

Outstanding. Thank you.
Thanks
You talk to much. Just get to the point!
